SPECIFICATION forming part of Letters Patent No. 271,896, dated February 6, 1883.

:4 Application filed February 13, 1882. (No model.)

To all whom it may concern Be it known that I, Svrvnsrna H. MILLI- GAN, acitizen of the United States, residing near McGlune'y, in the county of Perry and State of Ohio, have invented certain new and useful Improvements in Oar-Couplings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawin'gs, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to car-couplings; and it consists in certain improvements in the construction of the same, as hereinafter shown and described.

In the accompanying drawings, Figure 1 represents a perspective view of .a draw-head and coupling havingmy improvements. Fig. 2 is a plan view of the same, the lid holding the coupling-bolt being raised. Fig. 3 is a central longitudinal section.

In the said drawings, A designates a drawhead, having the lid B at its forward end, the lid being hinged at a, and forming a part of the top of the draw-head.

To the under side of the lid B is fastened the coupling-bolt c, which, when the lid is closed, projects downward within the drawhead, setting against a shoulder, b, formed in the bottom, the bolt then being in proper position to retain the coupling-link. The said bolt is so formed that when the link enters the draw-head in the operation of coupling and comes in contact with the bolt the latter is pressed upward, raising the lid B, and when the end of the link has passed the lid closes from its own gravity and places the bolt in proper coupling position within the link, the coupling being thus automatically effected.

When it is desired to uncouple, the lid B is raised to the position shown in Fig. 3. This may be effected from above by means of a cord or chain attached to the eyebolt d. The lid is slightly inclined forward whenin its raised position, and is stayed by a stop, a, at

the end of a rod, f. The said rod f passes through a'slot, g, in the lid, and turns down into a cell or recess, 71, made in the casing of the draw-head, the lower end of the rod being secured therein by a pivot, Within the draw-head is placed a buffer, k, the same being pivoted at n. A rod, in, connects the buffer with'the pivoted rod f, which holds the stop 6. (See Fig.3.)

b is a transverse beveled or A-shaped ridge in the bottom of the draw-head and in rear of shoulder 1). Ridge I) is just in' front of the vertically-pivoted buffer, and its function is to deflect the link as it enters the draw-head, so that it will strike against the vertical front edge of the buffer, above its pivot, to effectthe coupling.

When the lid B is in the position shown in Fig. 3 and the link (3 enters the draw-head,

coming in contact with the buffer is, the latter being pushed backward draws the rod on and causes the stop 6 on the pivoted rod f to press backward the lid B, which immmediately closes, and the coupling is effected.

Having described my invention, I claim- 1. The combination, with the draw-head, having the hinged lid, of the buffer vertically pivoted in and to the draw-head, and connected by a pivoted rod, at, extending forwardly from its-top, with mechanism at the hinged end of the lid, so as to draw the latter down by movement of the vertically-pivoted buffer, substantially as set forth.

2. The combination, with the draw-head, having the hinged lid carrying the couplingbolt, with a front shoulder, b, and a transverse beveled ridge, b, in rear of said shoulder 1), of the buffer vertically pivoted to the draw-head just in rear of said beveled ridge b, and connected with the lid by mechanism for closing the same, said beveled ridge b serving to guide the link against the vertical edge of the buffer above its pivot, as set forth.

, 3. The draw-head provided with the pivoted buffer 70, connected with pivoted rod f, having stop 0', in combination with the hinged lid B, having slot g, and holding the bolt a, substantially as shown and described.

4. The combination of the draw-head, the vertically-pivoted buffer in the draw-head, the

hinged lid carrying the fixed coupling-bolt In testimony whereof I affix my signaturein and having slot g at its hinged end, the conpresence of two witnesses; nesting-rod m, extending from the top of the buffer forwardly and pivoted to the rod f, and SYLVESTER H. MILLIGAN. said rod f pivoted in recess h, and passing up and through slot g, and provided with a Witnesses:

stop end, 6, which bears against thelid, as set THOMAS FLOUEY,
